Collisionless Resonances Set the Size of a Weyl Exceptional Ring
Xianhao Rao, Hong Li, Xuan Sun
Eliminating continuum degrees of freedom converts conservative dynamics into a dispersive, non-Hermitian response whose topology need not represent the causally selected kinetic dy…

Phase-Space Topology and Spectral Flow in Screened Magnetized Plasmas
Xianhao Rao, Adil Yolbarsop, Hong Li +1
Topological wave phenomena in continuous media are fundamentally challenged by unbounded spectra and the absence of a compact Brillouin zone, which obstruct conventional bulk--inte…

Enhanced dynamo drive for the sawtooth relaxation process due to non-uniform resistivity distribution in a reversed field pinch
Wentan Yan, Ping Zhu, Hong Li +3
In this work, we use the three-dimensional resistive MHD code NIMROD to investigate the impact of resistivity inhomogeneity on the sawtooth process of an reversed field pinch (RFP)…
